It is hoped that these sample question papers will certainly improve the classroom transaction of the subject matter in our schools. These Sample Question Papers have been prepared by practicing teachers of DAV Public Schools under the guidance of experienced resource persons in workshops conducted by the DAV Centre for Academic Excellence.
Constant : A symbol having a fixed numerical value is called a constant. Variable: A symbol which takes various numerical values is called a variable. The perimeter P of a rectangle of sides l and b is given by P = 2 (l + b). Here, 2 is a constant and l and b are variables. Algebraic Expressions: A combination of constants and variables with four fundamental operations of addition, subtraction, multiplication and division is called an algebraic expression. Terms: Various parts of an algebraic expression which are separated by the signs of + or – are called the ‘terms’ of the expression. Ex. 2x2 – 3xy + 5y2 is an algebraic expression consisting of three terms, namely, 2x2,–3xy and 5y2. Kinds of algebraic expression: Monomial : An algebraic expression containing only one term is called a monomial. Ex. – 5, 3y, 7xy, 3/2 x2yz, etc. are all monomials. Binomial : An algebraic expression containing two terms is called a binomial. Ex. The expression 2x – 3, 3x + 2y, xyz –5 etc. are all binomials. Trinomial: An algebraic expression containing three terms is called a trinomial. Ex. The expressions a – b + c , 2x2 + y2 – xy, etc. are trinomial. Factors of term: Each terms in an algebraic expression is a product of constant and variable . These number(s) and variables are known as the factors of those terms. A constant factor is called a numerical factor, while a variable factor is known as a literal factor. Class 8 Algebraic Expressions and Identities  1

The collection of welldefined distinct objects is known as a set. The word welldefined refers to a specific property which makes it easy to identify whether the given object belongs to the set or not. The word ‘distinct’ means that the objects of a set must be all different. Sets are denoted by Capital l letters Examples: A = {Color of rainbow] Þ express set of the Color of rainbow A = [1,2,3,……..} Þ Represent the set of natural numbers B = [a, e, i, o, u] Þ Represent the set of vowels M = {1/2, 2/3,3/4………….99/100} Elements of Set: The different objects that form a set are called the elements of a set. The elements of the set are written in any order under curly bracket. Elements are denoted by small letters. B = [a, e, i, o, u] Þ Represent the set of vowels Here element of set B are a, e, i, o, u Notation of a Set: Download full study material Download Set Theory  ● Sets ● Objects Form a Set ● Elements of a Set ● Properties of Sets ● Representation of a Set ● Different Notations in Sets ● Standard Sets of Numbers ● Types of Sets ● Pairs of Sets ● Subset ● Subsets of a Given Set ● Operations on Sets ● Union of Sets ● Intersection of Sets ● Difference of two Sets ● Complement of a Set ● Cardinal number of a set ● Cardinal Properties of Sets ● Venn Diagrams Negative integral Exponents, Laws of integral Exponents, Expressing Numbers in the Standard Form, Converting Numbers from Standard Form to Usual Form.
